' Machines for kneading and turning sugar mass on a rotatable table have become known. The kneading of the mass is however carried out in these machines with insufficient means,

for instance by kneading. arms by which the kneading throu h of'the mass cannot be completely attaine Arrangements are further provided to turn the mass upside down or to roll the same. It has however been impossible to completely and thoroughly turn the mass upside down with the aid of these means, as a portion of the mass at the centre remained in its position and cooled too strongly. It was then necessary to work with the hands so that the mechanical work became useless again. The most important condition however, that the cooled mass lying on a cooled rotary table is turned over completely after a certain time or rolled into the sugar mass, was not fulfilled.

By this invention these inconveniences are obviated. With this object in view a kneading roll adjustable in vertical direction and a turning over knife oscillatable and constructed like a plow share are arranged above the rotary table plate fitted with a cooling arrangement. The sugar mass can thereby be treated quite perfectly in hygienic respect. The machine is simple to attend so that this An embodiment of the invention is illustrated by way of example in the accompanying drawing in which:

Fig. 1 is a longitudinal section,

Fig. 2 a top plan view and Fig. 3 a side elevation of the machine.

Fig. 1 illustrates diagrammatically the turning knife.

Figs. 5 and 6 show in section and elevation respectively the vertical adjusting of the kneading -1 011.

, Onto a circular table plate 1, rotating slowly and cooled by water, the boiled sugar mass is poured and essence and colouring substances are added to the same. The mass is conveyed by the rotation of the table plate to under a kneading roll3 rotating in the same direction as the cooling table plate and being smooth or having coarseteeth. The kneading roll may also be water cooled. The

can be done even by a young man or woman;

sugar mass is pressed fiat by the roll to a predetermined thickness. As the roll is adj ustably mounted, the thickness of the su ar mass 31 can be altered at will. The attened sugar dough is then conveyed bythe rotation of the cooling table plate to a turning knife 4; constructed like a plow share. This turning knife is oscillatably mounted and adjusted and operated by hand. The dough is either turned over or rolled up' according to the position of the turning knife. When the turning knife is almost tangential to the rotary table, the sugar dough is turned, and it is rolled up in spiral-shape. When the turning knife is directed along a diameter of the rotary table plate, the turned or rolled up sugar mass further cooling slowly on the rotary table plate is then brought to the kneadmg device and the operation is repeated.

A special very important advantage of the kneading roll may here be mentioned: As the cooling table plate is absolutely smooth, the sugar dough when arriving at the turnmg device would be pushed off by the same.

It would therefore slip on the rotatin cool- 7 ing plate. The kneading roll serves urther to prevent the sugar dough from slipping off, so that the flattened sugar dough is positively conveyed to the turning knife. Even when the mass, shortly before the termination of the work, has become stiffer, the turning or rolling up is carried out quite perfectly.

The axle 32 of the rotary table plate 1 journaled in a transverse piece 10 of a frame 6 is driven by bevel wheels 8, 9, a secondary 5 shaft 36 and gear wheels 28, 29 from the main shaft 30 which is guided in the frame 6 and in an outer bearing 11 and carries the belt pulley 12. The rotary table plate 1 engages with the stationary cup-shaped support 7 fixed on the frame 6 and in which perforated cooling pipes 2 are. located, through which the cooling water is squirted against the rotary table plate 1. .On three uprights 5 fixed on the support I athreearmed transverse piece 14: is mounted which carries a stationary shaft 21 mounted in two bearing brackets 22 and 23. On this shaft 21 two levers 19 and 20 are shiftably mounted, the ends of said levers gripping over the axle of the kneading roll 3. Two sprocket wheels 24 and 26 rigid with each other are shiftably mounted on the shaft 21. By chain and sprocket wheels 27 26, 24 and 25' the rotating movement of shaft 30 is transmitted to the kneading roll 3. The levers 19 and 20 are connected at the middle by a bolt 33 to Y which a screw spindle l8 guided in a bow 37 is hingedly connected. The bow 37 is movably mounted in a bearing 34 fixed on the transverse piece 14. With the aid of the shaft 15, on which a hand-wheel 30 is keyed 1 and which is journaled in the bearings 35 and 34. and by means of the bevel wheels 16, 17 and 38, the kneading roll 3 can be adjusted in vertical direction in oscillating around the shaft 21. The plow share-like turning knife 4 is adapted to oscillate around one of the uprights 5.

I claim A machine for kneading and turning sugar mass, comprising in combination a rotary table plate, a cooling device for cooling said table plate, a kneading roll adjustable in vertical direction, and an oscillatable turning 1 knife constructed like a plow share, said roll and turning knife arranged above said table plate. r

In testimony whereof I afiix my signature.
